THE INVENTION RELATES TO A METHOD FOR THE PRODUCTION OF PURE ALKALCYANID off an alkali hydroxide and liquid HYDROGEN CYANIDE IN THE PROCESS STEPS NEUTRALISATION.VERDAMPFUNG, SOLID SEPARATION AND TROCKNUNG.DAS OBJECT OF THE INVENTION IS AN ECONOMIC AND ENVIRONMENTALLY FRIENDLY PROCESS FOR PRODUCING alkali metal WITH GREAT PURITY AND HIGH YIELDS TO DEVELOP . THE WATER AND EXTRACT PRODUCTS SUBJECT TO THE PROCESS WILL BE TREATED AND CONTINUED BY EVAPORATION AND BRUEDEN WATER, DRYING AND DRYING WATER. 0.05 MA.% ALKALICYANIDE RELATED TO THE QUANTITY OF ALKALICYANIDE PRODUCED. FURTHERMORE, THE USE OF NITROGEN AS A SUPPLY GAS FOR THE LIQUID HYDROGEN CYANIDE AND THE ADJUSTMENT OF THE FORMAT CONTENT IN THE SLAUGHTER TREATMENT MAKES A MAXIMUM OF 4 MA .-% HIGH PURITY OF THE END PRODUCT. |
